Search strategies for new subatomic particles often depend on being able to efficiently discriminate between signal and background processes. Particle physics experiments are expensive, the competition between rival experiments is intense, and the stakes are high. This has lead to increased interest in advanced statistical methods to extend the discovery reach of experiments. This talk will present a walk-through of the development of a prototype machine learning classifier for differentiating between decays of quarks and gluons at experiments like those at the Large Hadron Collider at CERN. The power to discriminate between these two types of particle would have a huge impact on many searches for new physics at CERN and beyond. I will discuss why I chose to perform this analysis in R, how switching to R has helped my work, and how I have overcome the problems that I encountered when working with large datasets in R.
